Defined in header <cmath>
float       fmin( float x, float y );	(1)	(since C++11)
double      fmin( double x, double y );	(2)	(since C++11)
long double fmin( long double x, long double y );	(3)	(since C++11)
Promoted    fmin( Arithmetic x, Arithmetic y );	(4)	(since C++11)

Returns the smaller of two floating point arguments.

4) If any argument has integral type, it is cast to double. If any other argument is long double, then the return type is long double, otherwise it is double.

If one of the arguments is NaN, this function returns the other argument. If both arguments are NaNs, the function returns NaN.

Parameters

x, y

-

values of floating-point or integral types

Return value

The smaller of two floating point values.
